Fatented Jan. 14, 1930 UNETED STTES PAUL WIEGHARDT, 0F MAGDEBURG, GERMANY, ASSIGNOR TO THE FIRM FRIED. KRUPP GRUSONWEBK AKTIENGESELLSCHAFT, OF MAGDEBURG-RUCKAU, GERMANY MULTIPLE-TAPE-WINDING MACHINE Application filed November 5, 1928, Serial No. 317,378,'and in Germany February 15, 1928.

I This invention relates to a multiple tape winding machine as described and claimed in application Serial No. 173,152, filed March 5, 1927. In that machine the central axes of the spools arranged in thewinding frames lie in one or more planes at right angles to the axis of the cable. The spools are so arranged that the central plane, at right angle'to the axes, meets the cable, at the winding-on pointof the tape, as nearly as possible at a tangent. Furthermore the spools are so arranged in pairs on spindles extending parallel to the cable, that each of these spools may be adjusted by a separate holder. With these machines each spool must be separately adjusted, so that the adjustment of the whole series is both tedious and lengthy. It has already been suggested to connect all the spools to a common adjusting device. This however is only possible with machines having a separate spindle for each spool, since, where the spools ot' a pair lie on opposite sides of the spindles, the spools of each pair must be adjusted in opposite directions with any alteration in the width of the tape. The present invention has for its object to produce a multiple tape winder of the former kind. in which much greater simplicity and economy of time is attained in the adjustment of the spools.

According to this invention the spool holders which precede, as well as those which follow the corresponding spindles are connected to a common adjusting device.

In order that the said invention may be clearly understood and readily carried into effect, the same will now be described more fully with reference to the accompanying drawings, in which Figure 1 is a section, through the axis of the cable of a machine according to the invention and shows the machine as seen in the direction of the cable axis.

Figure 2 is a side view partially in section, of Figure 1.

Figure 3 is a View. partly in section and on a larger scale, of a modification of a part of the machine shown in Figure 2.

Figure 4. is a side elevation of the part shown in Figure 3, and

of spools according to Figure 1, with differ- Figure 5 is a diagrammatic view of a pair ent widths of tape and diflerent diameters of cable.

The winding frame 1 is provided with four spindles 2, each made to take a pair of spools. The spools 3 and 4 of each pair are arranged one on each side of the spindle 2 on a separate holder, 5 or 6, so that the bearing pins 7 and 8 of holders 5 and 6 extend in opposite directions, viewed from the spindle 2.

As is to be seen more particularly from Figure '2, the holder 6 is rotatably mounted on the spindle 2 by means of a part thereof formlng a sleeve, and the holder 5 is mounted on holder 6 also by means of a part forming a sleeve. To the holder 6 is attached a toothed segment 9, and to the holder 5 a toothed segment 10. On a boss 11 of the winding frame are rotatably mounted two toothed rings 12 and 13. The teeth of the ring 12 engage with the teeth of the segment 9 at m and the teeth.

of the ring 13 with the teeth of the segment 10 at 11 (Figures 1 and 2). By rotating the rings 12 and 13, which rotation may be effected in any desired manner the spool holders may be rocked independently of each other, for the purpose of adjusting the spools. In the construction according to Figures 1 and 2, toothed wheels 14 and 15 are rotatably mounted on the winding frame 1, and these engage with the teeth of the rings 12 and 13 and may themselves be actuated by a worm and wheel drive 16 (Figure 1) or 17 (Figures 1, 2). If the ring 12 is rotated by means of the toothed wheel 14 then all the holders 6 are simultaneously rotated by means of the toothed segment 9, and thereby all the spools 4 the bearing pins of which project in one sense of rotation are adjusted. If the ring 13 is rotated by the toothed wheel 15, then through the toothed segment 10 all the holders 5 are rotated, and thereby all the spools 3 the bearing pins of which project in the opposite sense of rotation are adjusted. The angle of adjustment may be read on a scale attached to the toothed wheel of the gears 16 and 17, over which scale moves a pointer fixed to the winding frame 1. See 17 and 17 in Figure 2.

fixed on a spindle 20, which is rotatably fitted in a hollow spindle'21, on which is mounted the toothed wheel 18. The hollow spindle 21 is also rotatably mounted in the winding frame 1. Both spindles pass through the winding frame and each carries at its other end a worm gear pinion 22 and 23, respectively. The teeth of the pinions 22 and 23 have opposite inclinations and engage with worms 24 and 25 respectively, the worms of which, corresponding to the respective pinions, run in opposite directions. The spindles 26 and 27 of the worms are car ried beside each other in a projection 28 on vided with a toothed wheel 29, the radius of whose pitch circle is half the distance between the axes of the two spindles 26 and 27.

On the square end of the spindle can be fitted a handle 30, which carries a toothed wheel 31 corresponding to the toothed wheel 29.

If the angle formed by pins 7 and 8 (Figure 1) is to be altered, handle 30 is put on the square end of the spindle 27. By moving the handle the holder 5 is rocked; the

spindle 26 and consequently the holder 6 re-' main stationary. As will be later described in connection with Figure 5 an alteration in the angle formed by the spool spindles has always to be reckoned with if for instance a difl'erent width of tape is to be used. In order to facilitate the adjustment of the an le the following arrangement is provi ed. 7 a

The worm gear pinion 22 is provided with a scale 32 (Figures 3 and 4). Pointers 33 and 34 move over this scale, of which one, 33, is fixed to the winding frame, and the other, 34, is fixed to the worm gear pinion 23. By means of this scale the displacement of each of the worm gear pinions with respect to the winding frame, as also the displacement of the worm gear pinions with respect to each other, can be accurately determined. After adjustment of the spools to the angle desired at the moment, the handle 30 is placed on the square end of the spindle 26, so that the toothed wheels 29 and 31 engage with and with them the spools are rocked in' the same direction, whereby the previously adjusted angle between the spools is retained.

In the diagrammatic View shown in Figure 5, 35 and 36 are cables of different diameters and 37, 38 as also 39, 40 are spools of different widths. 41, 41' and 41", and 42, 42' and 42 show the axes of the bearing pins of the spools. The planes of the spools, at right angles to these axes, which form a tangent to the cable at the point where it is taped, are shown by 43, 43, 43" and 44, 44', 44", of which 43, 43' and 44, 44' show the planes with different diameters and 43" as also 44" show the lanes with spools of different widths. I the planes 43 and 44 are tangential .to the cable 35, then the axes 41 and 42 form the angle a. If the spools 37 and 38 are adjusted for taping the cable-36 their planes moves to the lines 43' and 44. The axes 44' and 42' correspond to these positions of the spools. The angle a enclosed by these axes is approximately equal to the angle a. From this it can be seen that on altering the cable diameter both spool holders may be displaced by the same angle without any fear of an appreciable variation of one of the planes from a tangential direction with respect to the cable. If therefore only the taping of cables of varying diameters were to be considered, even with multiple taping machines with spools arranged in pairs one on each side-of the spindle, a common adjustment of all the spools would be completely satisfactory. It must however be possible to work'such machines with spools of different widths. Quite generally the spools, with their side surfaces directed to the holder, are forced against a projection on the holder so that, according to the width of the tape, their planes lie at a different distance from the spindle 2. I In Fi -ure 5, 39 and 40 are spools for smaller widt s of tape and, 43" and 44" are the planes correspondcontrary to the spool adjustment, following I alteration of the cable diameter, which, as before described, takes place in the same direction. If on the other hand spools are used which are wider than the spools 37 and 38, then naturally the angle formed by the axes of the bearing pins of the spools is reduced as compared with the angle a. In working with spools of different widths a common adjustment of all the spools is therefore not feasible.

The method of construction according to the present invention permits the tangential adjustment of the spools in two spool groups. Further, it is possible with the arrangement shown in Figures 3 and 4 to adjust all the spools together, which is admissible if only the cable diameter is to be altered.
